Scrotal pouch as a urinary reservoir: a surgical revolution or bizarre hypothesis?

INTRODUCTION: Despite of the tissue engineering efforts to substitute the bladder, almost all the urinary diversion techniques still need gastrointestinal segments that have many well documented complications including the life threatening ones such as renal insufficiency and electrolytes imbalances. In this preliminary incomplete animal model, we aimed to introduce the idea of the possibility of scrotal urinary diversion via inguinal canal and speculate its clinical advantages with its low morbidity and surgical technique of human application. TECHNICAL CONSIDERATIONS: After a laporotomy and its left ureter dissection, a male rabbit underwent urinary diversion from kidney to the scrotum via catheter through the inguinal canal. Abdominal and scrotal incision closed with sutures but a potential gap was left at the scrotum for urinary leakage. Urinary leakage was observed from the ipsilateral scrotum postoperatively. THE HYPOTHESIS: Although this study can be regarded as just a hypothesis, we would like to introduce the idea of scrotal pouch as a urinary reservoir. We speculated that scrotal urinary diversion is better and applicable technique with many advantages and low morbidity, mortality and short operation time over the intestinal ones especially in selected patients. Further human studies may improve this novel technique.

The prevalence of sexual dysfunction and associated risk factors in women with chronic pelvic pain: a cross-sectional study.

The aims of the study were to determine the prevalence of sexual dysfunction, its subtypes and associated risk factors in women with chronic pelvic pain (CPP) as compared to a general female population. We evaluated 112 women (mean age 34.73 +/- 8.07; age range 18-50) complaining of CPP with a comprehensive history including female sexual function index (FSFI) and several general assessment questions (GAQs), a complete physical examination and routine laboratory tests. A group of 108 healthy women (mean age 33.28 +/- 7.95; age range 19-52) without CPP were enrolled as cross-sectional controls. According to the general population, the incidence of female sexual dysfunction (FSD) was 67.8% in women with CPP and 32.2% in women without CPP (P < 0.0001). Among 112 CPP patients, 78 (69.6%) of them had FSD and 34 (30.4%) patients did not have FSD in the study (P < 0.0001). In that 78 patients, 42 patients (53.8%) had hypoactive sexual desire disorder, 26 patients (33.3%) had sexual arousal disorder, 17 patients (21.7%) had orgasmic disorder and finally 58 patients (74.3%) had sexual pain disorder. The FSFI scores in both groups were as follows: (patients vs. controls; median value; P value, respectively): desire: 3.31 versus 3.98 (P < 0.0001); arousal: 3.58 versus 4.35 (P < 0.0001); lubrication: 4.20 versus 4.88 (P < 0.0001); orgasm: 3.70 versus 4.48 (P < 0.0001); sexual satisfaction: 3.80 versus 4.64 (P < 0.0001); sexual pain: 2.75 versus 4.98 (P < 0.0001) and total FSFI score: 21.35 versus 27.29 (P < 0.0001). The prevalence of FSD was higher in women with CPP than in a general healthy population not complaining of CPP. Investigation of female sexuality was essential for these patients.

Outcomes of urethral calculi patients in an endemic region and an undiagnosed primary fossa navicularis calculus.

Urethral calculus is a rare form of urolithiasis with an incidence lower than 0.3%. We determined the outcomes of 15 patients with urethral stone, of which 8 were pediatric, including an undiagnosed primary fossa navicularis calculus. Fifteen consecutive male patients, of whom eight were children, with urethral calculi were assessed between 2000 and 2005 with a mean of 19 months' follow-up. All stones were fusiform in shape and solitary. Acute urinary retention, interrupted or weak stream, pain (penile, urethral, perineal) and gross hematuria were the main presenting symptoms in 7 (46.7%), 4 (26.7%), 3 (20%) and 1 (6.6%) patient, respectively. Six of them had accompanying urethral pathologies such as stenosis (primary or with hypospadias) and diverticulum. Two patients were associated with upper urinary tract calculi but none of them secondary to bladder calculi. A 50-year-old patient with a primary urethral stone disease had urethral meatal stenosis accompanied by lifelong lower urinary tract symptoms. Unlike the past reports, urethral stones secondary to bladder calculi were decreasing, especially in the pediatric population. However, the pediatric patients in their first decade are still under risk secondary to the upper urinary tract calculi or the primary ones.

Progress in female sexual dysfunction.

INTRODUCTION: Female sexual dysfunction (FSD) is a significant age-related, progressive and highly prevalent problem that affects a substantial number of women that causes personal distress and has negative effects on quality of life and interpersonal relationships. DEFINITIONS: The female sexual response cycle consists of three phases: desire, arousal, and orgasm, and is initiated by non-adrenergic/non-cholinergic, e.g. vasoactive intestinal polypeptide and nitric oxide, neurotransmitters that maintain vascular and non-vascular smooth muscle relaxation resulting in increased pelvic blood flow, vaginal lubrication, and clitoral and labial engorgement. Furthermore, hormonal status may influence female sexual function. For the diagnosis of FSD, a detailed history should be taken initially, followed by a physical examination and laboratory studies. CONCLUSION: Due to the fact that there has been little research and attention on FSD, our knowledge in this field is quite limited and there is still no approved therapy. Future advances in evaluation and treatment of female sexual problems are forthcoming.

Prognostic factors effecting on recurrence of urinary stone disease: a multivariate analysis of everyday patient parameters.

INTRODUCTION: Since comprehensive urometabolic analyses are currently more preferred for the patients with recurrent stones and with high risk of stone recurrence, we have tried to determine simple patient data increasing stone recurrence to limit sophisticated analyses to certain cases at least in particularly deprivation districts. MATERIALS AND METHODS: For the study 173 with first-time or recurrent urinary stone were taken. After stone treatment, various empirical metaphylaxis methods were counselled to the patients. The parameters evaluated were (a) age at onset of the disease, (b) gender, (c) urinary pH and (d) specific gravity, (e) serum calcium and (f) uric acid, (g) stone burden, (h) side, and (i) location, (j) treatment modality and (k) recurrence history. New stone formation or growing of the existing stone was considered as stone recurrence. In statistics, independent samples t, chi-square test, Kaplan-Meier, Log rank and Cox regression tests were used. RESULTS: The mean age was 35 years. The male to female ratio was 88/85. Recurrence occurred in 49 (28%) cases at a mean of 30 months. Stone burden was significantly larger in patients with recurrent stone. In subjects treated with open surgery and with previous recurrence history, stone recurrence rate was significantly higher. In survival analyses, higher serum calcium level, larger stone burden, renal stones and previous recurrence influenced stone prognosis poorly. However in multivariate analysis, none of them was the most significant independent factor. CONCLUSIONS: According to our study, detailed urometabolic analyses may be somewhat reserved for the patients with ordinary factors increasing risk of stone recurrence including relatively high serum calcium level, large stone burden, upper urinary stone, history of recurrence and open surgery. As a result, it has been thought that the stone risk evaluation guiding detailed laboratory examination may be partially performed with first-line clinical data under limited conditions.

A magnificent circumcision carnival in the early 18th century Ottoman period.

Circumcision has always been regarded as both an important social event and a milestone of a young man's life in Turkish culture, especially in the Ottoman period. Herein we study an exceptional circumcision festivity which lasted 15 days in the early autumn of the year 1720, for the 4 princes of Sultan III Ahmed, some sons of two high-ranking Ottoman officials and thousands of male children of poor citizens of Istanbul as representing the beneficent of the Sultan. All the organizations of the Empire participated in this huge event, including many shows and a feast, and the preparations were initiated months before. Traditionally, this kind of important social event of Ottoman culture had been described in a literary manner, and Surname-i Vehbi was the special name for the book of this circumcision festivity with 137 colored paintings and a total of 175 pages. The original of this work, which is in the library of Topkapi Palace Museum in Istanbul, was written by Vehbi and illustrated by Levni. The importance of this antique book is that it is the last important example of the illustrated festivity books of Ottoman literature.

The experimental model of hydatidosis in rabbit testis. A preliminary study.

OBJECTIVES: Although no part of the human anatomy is invulnerable to hydatid disease, it has been reported to occur mostly in vital organs such as liver, lungs and brain. Hydatid disease of the urinary tract is uncommon accounting for only 2% of all such cases. Testes are extremely rare sites for echinococcosis. To our knowledge there are only 3 cases of testicular hydatid cyst described. In this animal model, we studied echinococcosis in rabbit testis. METHODS: We directly infected the unilateral testis of 4 male rabbits with infective protoscolices via intratesticular injection and housed them under pathogen-free conditions for 10 weeks. All rabbits survived during the follow-up period and then, at the 10th week, all testes were removed for histopathologic investigation. RESULTS: Despite of the direct infection of the rabbit testes with Echinococcus granulosus, there was no demonstrable hydatid cyst after a 10-week period except from some fibrosis in the injection tract of the testicular tissue in 1 case. CONCLUSION: The testes are extremely rare anatomic locations for echinococcosis infection. The mechanism of this resistance should be another reason apart from blood-testicular barrier. We think that low temperature in the scrotum or different properties of the testicular tissue may be the reasons of this defense mechanism. If this hypothesis clarifies with the further studies, new treatment options may be defined in the medical literature for the hydatid cyst.

The effect of tension-free vaginal tape (TVT) procedure on sexual function in women with stress urinary incontinence.

The aim of this study was to evaluate the effects of tension-free vaginal tape (TVT) on sexual function in women with stress urinary incontinence (SUI) by questionnaire. Thirty-two sexually active and married women who were planned for TVT to treat SUI constituted the patient group, and 25 women who were healthy, sexually active and married, were selected as the control group; the ages of both groups matched. Sexual functions (desire, arousal, orgasm, pain and satisfaction) were evaluated with the Index of Female Sexual Function (IFSF), and continence status during sexual intercourse was asked about both preoperatively and postoperatively in the 6th month. The mean domain scores of sexual functions such as desire, arousal, orgasm, pain and overall satisfaction preoperatively and postoperatively were 3.37+/-0.69, 3.82+/-0.62, 3.40+/-0.95, 3.41+/-0.98, 3.16+/-1.09 and 3.32+/-0.79, 3.71+/-0.53, 3.06+/-1.04, 2.75+/-1.29, 2.88+/-0.63, respectively, and postoperative scores insignificantly decreased. Also, these scores in the control group were 3.64+/-0.66, 3.96+/-0.73, 4.12+/-0.78, 3.96+/-1.14 and 3.68+/-0.92. In comparison with the control group, whereas all of the preoperative domain scores were found to be decreased but were statistically insignificant except orgasmic function, postoperative scores significantly worsened, except for desire and arousal. However, preoperatively nine patients explained that they had incontinence during sexual intercourse, and this problem persisted in two postoperatively ( p = 0.043). This study shows that both SUI and the TVT procedure negatively affect sexual function in women.

Idiopathic retroperitoneal fibrosis mimicking a pelvic tumor: a case of pericystitis plastica.

Retroperitoneal fibrosis was first described in 1905 by Albarran, a French urologist, who performed ureterolysis for ureteral compression produced by the disease. However, this disease became an established clinical entity by Ormond's account in the English literature in 1948. Pericystitis plastica has been used the define an extremely rare type of Idiopathic retroperitoneal fibrosis (IRF) constricting the bladder. In this study, we discussed the recovery of 29-year-old woman with pericystitis plastica who was misdiagnosed as pelvic malignancy or a chronic/subacut pelvic inflammation at the first evaluation.

Can conventional examinations contribute to the diagnostic power of unenhanced helical computed tomography in urolithiasis?

INTRODUCTION: To investigate whether ordinary tests used in urolithiasis can increase the diagnostic value of unenhanced helical computed tomography (HCT). MATERIALS AND METHODS: Of all patients admitted with acute flank pain, 137 without radiocontrast allergy, pregnancy and renal insufficiency were included in the study. After urinalysis (Ur) and ultrasonography (USG), HCT without a contrast agent was taken by 5-mm collimation, thereafter excretory urography (EU) was obtained. Confirmation of a stone was done by various tests and/or treatment methods. Statistically, the predictive values of HCT, USG, EU and Ur and their combinations were evaluated using the area under the receiver operating characteristic curve (AROC). RESULTS: The patients' mean age was 38 (range 4-72) years. Sensitivity values of HCT, USG, EU and Ur were 97, 69, 71 and 81%, respectively. Their specificity values were 96, 87, 91 and 65%, respectively. The widest AROC was found for HCT (97%). The best test combination was [HCT or USG] according to the AROC value (93%), but none of the AROC values of the test combinations was higher than that of HCT. However, 95% confidence intervals of the AROC values of these tests and their combinations overlapped. CONCLUSIONS: Because the HCT combinations with other tests improved the diagnostic value of HCT, they should be preferred in some individuals suspected of having urolithiasis. However, the most feasible single test meeting the all usage purposes was HCT in terms of the AROC value, and the combination was [HCT or USG] in which either HCT or USG was positive.

Antioxidative effects of exogenous nitric oxide versus antioxidant vitamins on renal ischemia reperfusion injury.

The objectives of this study were to compare the protective influence of exogenous nitric oxide on renal ischemia reperfusion (I/R) injury with that of the antioxidant vitamins C and E. Sprague-Dawley rats were divided into three groups ( n=12 per group). Normal saline solution was given in group 1, a vitamin C (200 mg/kg/d) plus vitamin E (100 mg/kg/d) combination in group 2 for 3 days before operating and Na-nitroprusside (5 mg/kg/d) in group 3 before reperfusion. The left kidneys were exposed to warm ischemia for 40 min followed by reperfusion for 90 min. The right kidneys were used as internal controls. After both kidneys were removed, histopathological examinations were performed, and oxidative and antioxidative parameters were measured. In the postischemic reperfused rat kidneys, the renal lipid peroxidation level was significantly lower, and the renal GSH level higher in the group given Na-nitroprusside compared with groups 1 and 2. Renal specific xanthine oxidase activity was also significantly lower in the group treated with Na-nitroprusside than in the groups given vitamins or saline. There was a significant, negative correlation between lipid peroxidation and reduced glutathione levels. Our results suggest that the exogenous nitric oxide (Na-nitroprusside) inhibits xanthine oxidase, and has more apparent preventive features for renal I/R injury than the antioxidant vitamins C+E.

Minimal transurethral prostatectomy plus bladder neck incision versus standard transurethral prostatectomy in patients with benign prostatic hyperplasia: a randomised prospective study.

OBJECTIVE: To evaluate the effectiveness and complications of the combination of minimal transurethral resection of the prostate and bladder neck incision in comparison with those of the standard transurethral resection of the prostate (TURP). PATIENTS AND METHODS: Forty patients with prostates of <or=25 ml were randomized to two equal groups (20 cases in each). In group I minimal transurethral resection of the prostate followed by bladder neck incision at the 6 o'clock position and in group II standard TURP were performed. Patients were evaluated in terms of the change in symptom severity, maximal flow rate and sexual function in addition to operating time, length of hospital stay, problems of catheter positioning at the end of the operation and the rate of bladder neck contracture using chi(2) and independent t tests. RESULTS: Age, prostate volume postoperative follow-up time, improvement in international prostate symptom score and maximal flow rate, length of hospital stay and erectile dysfunction rates were not statistically different between the 2 groups. Operation time was shorter in group I (p = 0.001). Although the urethral catheter was easily positioned at the end of the operation in group I, it was not possible in group II for 4 patients (p = 0.053). Postoperative retrograde ejaculation for groups I and II were determined in 7 and 16 patients, respectively (p = 0.005). Bladder neck contracture was not found in group I, while it was seen in 2 patients in group II (p = 0.487). CONCLUSION: The combination of minimal transurethral resection and bladder neck incision in patients with small prostates appears to provide a satisfactory clinical outcome, comparable with standard TURP, while preventing the difficulty of urethral catheter positioning at the end of the operation, decreasing bladder neck contracture and lowering the incidence of retrograde ejaculation.

A limited study on the perception and change in attitude about circumcision among health care professionals and their male family members.

OBJECTIVES: Millions of male children are circumcised throughout the world. We investigated the opinions and thoughts about the past and future aspects of circumcision by interviewing 100 male family members of the health care staff. METHODS: 100 male volunteers answered a questionnaire comprising questions about their personal observations, feelings, festivities and opinions about their own circumcisions as well as their views about the circumcision phenomenon as a parent, and the legality of circumcision. RESULTS: 81% of the volunteers in our study had been circumcised by traditional circumcisers. The rest had been circumcised by doctors (10%), barbers (7%) and sheikhs (2%). In 90% the circumcision took place at home, 7% in hospitals and in 3% in village squares. While 66% of the subjects do not remember anything, the remaining 33% reported some bad sensations like fear, pain and shame about their circumcisions, and 1 (1%) subject reported happiness. As a parent, they answered the questions on their preferences on the place and performer of the circumcision. 44% preferred to have circumcision performed in the hospital by a physician, 26% at home by a physician, and 30% at home by a circumciser. CONCLUSION: There are significant changes in the attitudes of people in Turkey on circumcision as a traditional culture, though its perception has remained unchanged.
